Non-invasive current transformerfor measuring of AC current. Output voltage is alternate voltage proportional to current in main wire. This sensor could be use with Lan Controller v3 INPA1-4 inputs.

It can be useful for building your own energy monitor or for building an over-current protection device for an AC load. This current clamp can be used to detect a current of up to 30A. Simply clip it around the current source that you wish to measure and it will produce a (very) small AC voltage proportional to the current. The cable is terminated on one end with a standard 3.5mm jack (like a headphone jack).Use this to build your own energy monitor and keep your power usage down, or use it to to build an over-current protection device for an AC load.
